Great series and keep them coming, if you can't think of a sequal then remember, it doesn't have to continue directly after the last one it could continue from whenever. Just throwing out ideas but you could base each one off of different American wars. Like the Spanish war that brought us California and More states.

I like your thinking. It is nice to talk to a fellow Patriot. I was actually going to skip about three hundred years and introduce Equestria Johnathan Justice and Nightmare Moon to the modern United States. Maybe have them or their foals stop a terrorist plot to destroy Washington D.C.? I don't really know yet. But I do like the idea of promoting the Mexican/American war. Also I am stressing whether or not I should give Celestia and Jason foals. I still need to finish forging an overall conflict/plot.
